CHARLES S. KERSHNER, OF WESTPHALIA, KANSAS.

I MOTOR FOR MAGNE'IOS.

To all whom it may concern:

Be it known that 1, CHARLES S. KERSHNER, a citizen of the United States, residing at Westphalia, in the county of Anderson, State of Kansas, have invented certain new and useful Improvements in Motors for Magnetos; and I do hereby declare the following and exact description of the invention, such as will enable others skilled in the art to which it appertains to Specification of Letters Patent.

Application filed March 9, 1909. Serial No.

make and use the same.

This invention relates to motors and has special reference to a motorfor actuating the magneto of the sparking, mechanism used in connection with internal combustion en? gines.

The principal object of theinvention is to provide a novel and efiicient means whereby the magneto may be started manually and then continuously operated by the explosive engine.

With the above .and other objects in view,

- the invention consists in general of certain novel details of construction and arrangement of (parts hereinafter fully described, illustrate in the accompanying drawings,

.and specifically set forth in the claim.. I

In the accompanyi'n drawings, like characters of reference indicate like parts in the several views, and; Figure 1, is'a top plan view of the invention, the top of the casing being removed to show the working parts. Fig. 2 is a side elevation from the manually operable end. Fig. 3 is a detailed tive of. the manually o erable gear onthe 1 shaft. Fig. 4 is'a sim. ar view of the belt or chain driven gear.- Fig. 5 is a perspective view of a shipper used with this device. Fig. 6 is a similar view of the shipper operating cam.

The numeral 10 indicates the housing or casing of the invention and this housing is provided with suitable bearings 11 wherein is mounted a shaft 12. Securely fixed upon the shaft 12 is a drive pulley 13 provided with a rubber tire or belt adapted to contact with and operate the pulley-of a magneto. There is also keyed uponthe shaft 12 a flywheel 15, the same being preferably located outside of the housing 10.

Slidably and rotatably mounted uponfthe shaft 12 1s a belt pulley- 16 adaptedtoibe connected by a suitable belt to a pulley on 16 is provided with an extension 17' around perspecthe engine shaft. The'hub of this pulley which is formed 'an' annular groove 18.' A

provided with an annular groove 29. At

Patented Dec. 14, 1909. 482,265.

whereon is fixed a collar 21.

Upon the shaft 12 is mounted an arm 22 so arranged as to be freely rotatable on said shaft. -Upon the outer end of this arm is carried a wedge shaped arcuate member 23 provided with a centrally dis osed slot 24. Attached'to the arcuate mem er.23 is a handle 25.

The stem 20 projec 21 being held closelyupon the outer face of ,the member 23. It will now be obvious that if the handle 25 be mov'edso that the collar 21 is caused to rise on the wedge shaped member 23, the pulley 16 will be drawn toward the member 23. For the purpose of permitting the pulley 16 to resume its original position when the handle 25 is moved in the opposite direction there is provided a spring 26 located between the hub extension shipper fork 19 is held in the groove 18 and i this shlpper fork is provided with a stem 20 s through the housing 7 10 and passes througi the slot 24, the collar 17 and the bearing 11. Upon the opposite side of the pulley 13 there is provided a gear aving an extension 28 upon its hub this end of the device there is also provided a fork 30 having a stem 31'and'collar 32 lar to the spring 26.

The hub 38 of the pulley 13 is provided with clutch teeth 39 upon each' end thereof and the hubs of the pulleys 16 and 27 are likewise provided with clutch teeth 40 upon the end adjacent the pulley 13. 41 are also mounted upon the'housing 10 and these bearings serve to support a short shaft 42 whereon is mounteda gear 43 arranged to Inesh-withthe gear 27. A handle crank 44 is also securely keyed to the shaft 42 so that upon the rotation of the crank 44 the gear will likewisearotate therewith.

, Collars '5 are secured at the outer ends f the shaft to prevent the various parts from moving therealong.

Bearings 'llO In the operation of this device let it be supposedthat.the engine is at rest and that the un 13 is in contact with the driving pulley. o the magneto while the pulley 16 is e1te to the'engine. Now, in order to start the magneto and produce the'proper spark i the .hand1e 25 is so turned as to disengage the clutch teeth 40 of the pulley'16 from the clutch teeth. 39, with Which they are normally in engagement. then.turned' to permit the engagement of the clutch teeth:40 of the pulley 27 with the I clutch teeth 39 of the pulley 13. The crank handle 44 is then given several rapid turns. This store's-upenergy' in the fly-Wheel l5 and the pulley '13 is rapidly rotated, first by the crank handle and then by the stored up 13. This having been done the engine itself keeps up the rotation of the pulley 13 and consequently of the magneto, thus producing the regular ma neto spark.

- By means 0 this arrangement the 0rdinary storage battery-is rendered useless so that it is not necessary to have a storage battery .around a gas engine. There has thus been provided a slmple .and eflicient device I of the character described-and for the purpose specified.

1 It is obvious that many minor changes The handle is may be made in the form and construction of the invention without departing from the material principles thereof. It is not, therefore, desired to confine the invention to the exact form herein shefwn and described, but

come within the scope of the appended claim.

f Having thus described the invention, what is claimed as new, is

' In a motor for magnetos, a rotatably'supported shaft, a drivepulley fixed thereon to it is wished to include-all such as properly rotate therewith a fly-wheel fixed on said shaft, a manually .operable gear --.slid ably and rotatably mounted on the shaft, -a belt pulley adapted for connection toan en clutch elements adapted to connect the rive pulley with either the gear or belt pulley, springs normally forcing said belt pulley and gear into engagement with the drive pulley, shipper forks engaging the hubs of said belt pulley and gear, a stem projecting laterally from each of said shipper forks,

arcuate cams each provided with a slot adapted to receive one of said stems, saidrcams being p1voted on said shaft, collarson sald stems bear ng against said cams, and a handle on eachof said cams adapted to totate the same andforce the belt pulley and gear away from the drive pulley.

Intestimon whereof, I aflix my signature,

in presence 0 two witnesses.
